This face on spiral galaxy lies at a distance of about 66 million light years and is about 75,000 light years across or about half the size of the Milky Way Galaxy.
This image was a stack of 6 x 10 minute exposures taken with the MX716 camera and the 16" telescope.
I am having a hard time proving what everyone else seems to accept as fact because the spec sheet says so.
Not only is there no obvious difference in the "depth" of the images but the total exposure time on the 716 was twice as long as the 516 exposure.
This then also brings into question the accepted belief that stacking short exposures produces the same depth as single longer exposures. I have never believed this theory and these images pretty well put it to bed as far as I am concerned.
Unwilling to accept the results, I spent 3 different nights acquiring images with the 716 and this image is the best of the three nights.
